Title: Separating filter using fibrous structure
Inventor: MORI TAKEHIKO
IPC: B01D29/46
Filed: 1979-10-11
Abstract: PURPOSE: To offer the simply constituted separating filter of high efficiency, by filling the fibrous structure in the wedge type pathway possessing a conical section by which the liquid velocity on the outlet side is increased higher than that on the inlet side, and by installing the throttlingm echanism for intercepting the reaction of the filtered liquid directing the outlet side.  
     CONSTITUTION: The conical sheets 1, 2, are set by interposing the spacer sheet 4 in order to form the required gap 3 between the sheets 1, 2. Inside the round ring 7 of thus formed wedge type section, the fibrous structure (a) is filled with a required void ratio, and its outer circumference is pressed by the wire mesh 8. When the liquid flows in the casing 13 in the arrowed direction toward the fibrous structure (a), the large solid is caught by the wire mesh 8, and the liquid passed the fibrous structure (a) flows toward the gap 3 formed at the apex of the wedge type round ring 7. Hereupon, the liquid flow is accelerated because of passing the fibrous structure (a) in the wedge type round ring 7 and of being throttled by the wedge type section. If the liquid comprises two components A, B, and the fibrous structure (a) is filled up with the liquid A before starting the filtration, the liquid A plays as the dispersing medium and only the liquid A passes the fibrous structure (a) and the liquid B is left behind; hereby, two liquids A, B, are separated from each other.

Title: Tire wheel
Inventor: AOKI TAKAAKI
IPC: B60C23/00
Filed: 1988-05-27
Abstract: PURPOSE:To improve the drivability in the high speed range in a tire wheel of a vehicle or the like by forming in communication with the inside of a tire a piston-contained hollow part inside each of struts between the externally diameter part and the center part of a rim on which a tubeless tire is mounted, to make the piston position variable according to wheel speeds. CONSTITUTION:The centrifugal force acting on a piston 5 varies according to the revolution speed of a tire wheel 1 and the position of the piston 5 inside a hollow part 4a varies. That is, the piston 5 moves in the direction of the external diameter part against a spring 10 to reduce the capacity of a hollow part communicated with a tire. As a result, the internal pressure of the tire is increased. The rigidity thereof is improved and the flattening of the tire may be prevented. When the running speed is reduced, the piston 5 is moved inward to reduce the inner pressure of the tire to be ready for the low speed turning. The tire may then be adjusted automatically for the inner pressure of the tire suitable for the high speed running to improve the performance.
